Activity type images not showing up in v16

We are in the process of upgrading from Premium 2013 to v16. I'm customizing the columns and previously for history (and activity lists/task lists) I could choose "Type" and it would show our custom icon. Now, selecting "Type" has the full name of the activity text when I try to look at any history on opportunities or the contacts. The task list and calendar both maintain the icons. What can I do to get the icons back in the history?

Ohhhhh nooooo I realize it's a small thing but we use those for a quick reference, especially in opportunities, to track processing items versus general comments vs paperwork requirements, since we use different shapes and colors.
